Introduction
BBG-1034-AUD-PRO-DSP Functional Description
Control and Data Input/Output Interfaces
GPI Interface
Two independent ground-closure sensing GPI inputs (
GPI 1
and
GPI 2
; each
sharing common ground connection as chassis potential) are available.
Associated with each GPI user control is a selection of one of 32 user-defined
presets in which GPI activation invokes a control preset. Because the GPI
closure invokes a user-defined preset, the resulting setup is highly flexible
and totally user-defined. Invoking a user preset to effect a change involves
device setup communication limited only to the items being changed.
GPI triggering can be user selected to consider the activity on discrete GPI
ports, or combinations of logic states considering both GPI inputs, as well as
be set for level or edge triggering. This flexibility allows multistage,
progressive actions to be invoked if desired. Indication is provided showing
whenever a GPI input has been invoked.
GPO Interface
Two independent phototransistor non-referenced (floating) contact pairs
(
GPO 1/1
and
GPO 2/2
) are available. A GPO can be invoked by setting a GPO
to be enabled when a preset is in turn applied (i.e., when a preset is invoked
(either manually or via event-based loading), the GPO is correspondingly also
activated.
Serial (COMM) Ports
The BBG-1034-AUD-PRO-DSP is equipped with two, 3-wire serial ports
(
COM 1 - Serial Port 1
,
COM 2 - Serial Port 2
). The ports provide for SMPTE
2020 de-embedding to an output port, and provide RS-485 LTC I/O (when
licensed with option
+LTC
). Either port can be configured as RS-232 Tx/Rx or
RS-422 non-duplexed Tx or Rx.
Alarm Function
The device can be set to monitor input video/audio for input errors such as
input LOS, frozen or black frame, loss of reference, closed captioning
ancillary data loss, and/or per-channel audio absences. These alarms can be
propagated as a device general error or warning message, and can be
downloaded as basic .txt logs or via a Syslog function.
User setup tables configure the alarm severity escalation as well as trigger
holdoff/release and other thresholds as applicable.
